Eluent degasser for advanced ion chromatography is simply included between the eluent and IC pump or between the sample and the injection valve
Gas bubbles in eluents produce an unstable baseline as high-pressure pumps for ion chromatography can transport liquids but not gases.
This is why it is advisable to degas eluents before use.
A very similar problem is encountered when samples which already contain gas bubbles or which could release gas are to be measured.
In such cases it is also necessary to remove the gas phase first.
Both the degassing of the eluents and the degassing of the samples can be carried out manually, eg with a water-jet vacuum pump or fully automatically with the 837 IC eluent degasser (version 0030).
The degasser module is simply included between the eluent and IC pump or between the sample and the injection valve.
The eluent and sample then flow through the special Teflon-AF capillaries which are located in separate vacuum chambers.
The vacuum removes even microscopically small gas bubbles, excess carbon dioxide or nitrogen.
Time-consuming manual eluent and solvent degassing are no longer necessary.
The 837 IC eluent degasser (version 0030) is equipped with a total of three vacuum chambers so that two eluent flows and one sample flow can be degassed simultaneously.
The electronically controlled vacuum pump means that the 837 IC eluent degasser runs extremely quietly.
